I'm a professional software
developer with many years of experience on Mainframes, Unix, Linux and
Windows systems. I had written small applications for my own use on
Palm OS, Java ME and Windows Mobile devices, but they never reached the
market.

When the iPhone appeared, I wanted to
write something for it, but the learning curve (Objective C) and
investment (new Intel Mac) kept me from proceeding.

When the first Android phone was
announced, I quickly became convinced that Android was what I wanted to
use in the future, due to the open source nature and astonishing design
of the system and the use of Java, my favorite
programming language. I wrote some applications I most urgently need on
my mobile device and I think that other people might also use them.
